VACUUM-CLEANER BAG.

Application filed August 1, 1921. Serial No. 488,765.

To all whom t may concern:

Be it known that l, Gnonon CLnMnNTs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Vacuum Cleaner Bags, of which the following is a speciication.

My invention relates to a bag for use with vacuum cleaners-and has for its object the provision of a one-piece bag which shall be simple and easy to make` which shall be attached to the handle of the cleaner both at the top and at the. bottom. and which shall be provided with a restricted interior vacuum neck which insures that all of the dust and foreign material inhaled shall be deposited in the body of the bag in such a position that it cannot drop back into the vacuum cleaner. lOther objects will appear from time to time in the course ofthe speciication. I illustrate my invention more or less diagrammatically in the following drawings wherein:

Fig. l is a side elevation of the bag in use;

Fig. 2 is an enlarged view of the bag;

Fig. 3 is a section on line 3-3 of Fig. 2.

Fig. et is a plan View of the blank from which the bag is formed.

Fig. 5 is a plan view of the throat blank on double the scale of Fig. l.

Fig. 6 is a` section .on the line 6-6 of Fig. 2.

All parts are illustrated with like letters and numbers throughout the drawings.

A bag blank A. of the form illustrated in Fig. 4 is turned over on itself along the seam or edge B, and is sewe'd along it, and about its entire edge except the open space C at the upper end of the bag which is normally closed by. clip C', and the open space D at the bottom of the bag which is hemn'ied as at D and Secured by the wires D2 to an inwardly projecting flange D4 of the plug D3 which is adapted for attachment, by means not forming part of the present invention, to the cleaner casing D5. rFhe bag thus finished is illustrated in Figi. 2. A second piece of cloth E3 is sewed to the bag along the seams E extending from the point E adjacent the neck of the bag; to a point E2 midway up the bag and illustrated as being so near to the edge B of the bag as to form a restricted neck or passage, through which the suction exhaust stream passes with substantially undiminished velocity. rlhe foreign material thus conveyed is dropped in the body of the bag when the exhaust stream passes the point E2 and is lost in the interior of the bag.

In the bag, as illustrated in Fig. 2, the neck is 'at one side of the bottom of the bag, and the other side forms when bag` is deflated, a loose depending flap. l therefore insert an eyelet F in the lower corner of the bag and secured thereto a chain F and a catch or snap F2 adapted to be secured to an eyelet or hook F3 on the handle F'1 of the cleaner. rFhe upper end of the bag is supported by the clip C and a chain U2 to a hook or eyelet C3 on the upper portion ot the handle.

While l have illustrated a form of bag which is in successful use, it will he realized that the drawing and description herein are largely diagrammatic and that many variations in size` disposition and in the relation of parts may be made without departing from the spirit of my invention.

The use and operation of my invention are as follows:

l provide a bag for vacuum cleaners which is made from a single bag blank. l provide for a seam within the bag forming a restricted neck reaching midway up the bag. Preferably I form this neck not by sewing the two sides of the bag together, but by inserting an additional piece of cloth which permits thebag to be fully inflated and does not detract from its symmetrical shape.

This bag is particularly adapted for use with that form of vacuum cleaner casing wherein the exhaust opening is at one side of the casing. The. lower corner of the bag opposite to the neck, in this form of bag- .tends to iap down on the casing or even on the ground. giving an unsightly effect and at times reducinpr the wear of the bag. l therefore provide means for supporting the bag on the handle, not only at the top of the bag. but at this bottoni corner.

I claim:

1. A bag` for suction cleaners adapted for use with a suction cleaner casing and handle, comprising` a bag body, and means for attaching the top of said bag body to the handle, a neck at one side of the lower` end of the handle adapted to be secured to the.

suction cleaner casing and means for securthereto and a member on the handle adapted to be engaged by said catch.

"3.- A bag adapted' for use with suction cleaners, having a neck` at one side of the lowerl portion of said bag adapted t0 be secured to the cleaner, and means for securing the top and the opposite lower corner of said bag to the handle.

Signed at Chicago, county of Cook and Stateof Illinois, this 28th day of June 1921.
